' Application filed October 20, 1924. 1 Serial No. 744,532.

I This inventionrelates to a plowr const'ruction. 7 Theprimary objectof the present invention is to provide an improved plow construction which will facilitate the assem- I bling of the various parts which go to make up the plow base with greater accuracy and precision, thereby insuring uniformity in manufacture and assembling and greaterefficiency in operation and also affording greater rigidity to the parts of the plow base, particularly the plow ,point. j H A further object of the invention is to provide a plow construction which will assist in properly aligning and locat ng the moldboard, share and standard, with respect to each other and incidentally strengthening these parts when assembled. H A still further object of the invent on is to rovide anfimproved plow construction whlchwillassist the farmer in replacing repair parts, particularly the plow po nts 111 amanner to insure correct working of the plow. V 7

These and other objects are accomplished by providing a construction and an arrangement of the various parts in .themanner hereinafter described and particularly pointed out in the appended claims. 7

Referring to the drawings, Fig. 1 1s. a perspective view of a plowshowing the plow point thereof partly disassembled from 1ts associated parts. I Fig. 2 is a perspective view ofthe standard and land-side of my improved plow construction. Fig.3 is a cross sectional viewitaken on the lines 3-3 in Fig. 1, 'and Fig. 4 is a perspective view of the lower side of the plow share or point. 7

The present invention is directed to an improved plow construction; which facilitates the assembling of the various parts of a plow base and eliminates the necessit-y' of using straight edges.- and squares for properly aligning the various parts of the plow in assembling them. v I r I This construction provides an accurate means for locating the variousparts with respect to each other-andaids in preventing the breaka e of the shares due to ill fitting, and also acilitates the establishment of a good joint between the mol-dboard and the plowshare which is essential for scouring and proper operation of the plow. Ihave found that in the assembly of plow bases,

the shares which are secured to the standards 7 by bolts may be positioned through a con siderable range of. adjustment due to looseness between bolts and bolt holes and irregularities in manufacture so that the point of the share or the. wing of the share may be elevated or depressed or the point ofthe' share may be deflected laterally.

"1' have also found that the position of the plow. share including the point and wing' in relation to the plow base is of vital importance and that the slightest variation in the relation of the point and wing of the share affects the operation of the plow in an unexpected manner. In plows as com- .mo'nly constructedv the moldboard is bolted to the standard and serves to locate the share with respect to the position of the wing and point." I have found that moldboards often become loosened in use, and

when shares are replaced suchshares willbe improperly located due to such shifting of the moldboard, with the result that the plow will thereafter work very imperfectly and the defect be almost impossible to diagnose and remedy by the farmer. My inven tion is designed to overcome these difliculties by providing means for positively loeating and supporting the share in relation to the standard so that the strainonthe bolts of. the share will be relieved as well as the strain on the moldboard' and the'share under all conditions retained in operative position on the standard independently of the moldboard. For the purpose of illustration, I have shown my improved plow construction comprising a baseYor standard 10 which has secured to its rearwardly extending portion 11, by means of bolts 12, a land-side 13. The

standard 10 is provided with a downwardly curved surface 14, which is preferably positioned at an inclined angle with respect to the line of travel of the plow and a forwardly curved edge 15. The downwardly curved surface 14 is provided with two up er apertures 16 andla lower aperture 17.

tin'uation of the curved surface 14 of the X; tending downwardly and laterally as a con:

standard 10 is an ear 18, which has a lower outwardly from the downwardly curved surface 14 of the standard 10 and along a line which is a continuation of the straight edge 19 of the ear 18 is an upwardly projecting lug 20. This lug 20 is substantially rectangular in cross section, as shown in the cross sectional View inFig. 3, and occupies a transverse position with respect to the as of travel of the plow. Mounted on the forward edge andsli htly overlapping the curved surface 14 of tie standard 10, as shown at 21, is a plow point or share 22. e plow point 22 is provided with the usual. laterally extendingwinged portion23 which is adapted to have a portion thereof overlafpping and lie against the lower port-ion 24 o the downwardly curved surface 14 of the standard 10. Formed on the rear side of and adjacent the upper edge 25o f the winged portion 23 of the pointj22 is a recess or cavit 26, which is adapted to enga e and snu y lit the upwardly extending ug of t e standard 10 for accurately positionin the oint 22 on the standard 10. Forlne on t e lower side of the winged portion 23 of the low point 22 and adapted to engage the undier side of the ear 18 of the standard 10 is a projection 27 which may be used partioularl on cast shares when only one securing olt is employed to anchor the point or share. The point 22 is further rovided on its rear edge with a curved ange 28 which is adapted to be engaged by and seated on the forward curved edge 15 of the standard 10. The plow point 22 isprovided with an aperture 29 which is adapted to register with the aperture 17 in the standard 10 for the receptionof a counter-sunk belt for securing the plow pointto the standard. \Vhen desired more than one of such bolts may be is employed. From this construction it will be noted that by positioningthe lug 20 at a position substantially transverseto the line of draft of the plow that the plow oint is reinforced and strengthened by this ug by reason of the fact that the force acting against the plow oint is transmitted directly to the standar without undue strain on the securing bolts. When the plow point 22 is properly secured to the standard 10 in the manner above described the edge is in ali ninent with the upper edge 30 of the lug 0, When the point is secured to the standard in this position the moldboard 3;], may then be positioned with its lower straight. edge 32 resting against the upper edge 30 of the lug 20andco-Inciding with theupper edge 25 of the winged portion 23 of the point 22. a The forward edge 33 of the moldboard 31 will then be resting against and contacting withthe rearward edge 34 of the u wardlyextending portion of the point 22; en the moldboard is thus positioned countersunk bolts 35 may be inserted in the registering apertures of the moldboard and the apertures 16 of the standard 10.

From the above description it will be seen that by placing the lug 20 on the standard 10 of the plow and forming a recess in the point therefor, I have provided a construction which permits thepositioning oftlte point of tlle plow with accuracy and precision on the standard and at the same time produces a lug construction which reinforces and strengthens the plow point in that the lug is arranged substantially transversely with respect to the line of dratt, is thereby transmitting the force directly from the plow share to the standard, and it will further be noted that the upper or rearward edge of the lug assistsin properly looatin the moldboard in relation to the stander and the plow point, and firmly secures the moldboard in a relatively fixed positionwith respect tothe other parts. y

While in the ahovespeeification I have described one embodiment which nyinvenr tion may assume in practice it will of course be understood that the same is capable of modification and that modification may be made without departing from" the spirit and scope of my invention as expressed int-he following claims. p i n a What I claim as my invention and desire to secure by Letters Patentis:
